Hello everyone.
I added a genuine Harley tach to my 2018 RK. Used proper harness and connectors. Soldered the connections. Everything works great but in DIAG mode: ECU- no errors, BCU- no errors, TACH- no errors but SPDO has a U0157 DTC.
The Gear position/RPM readout on the LCD display on the speedometer now says "GEAR 1,2,3, etc. instead of: 1@ ****rpm (rpm varying depending on engine speed).
It seems that the tach and speedometer aren't communicating properly.
Do I just need a dealer to add the tach software properly via the data port?
The bike is wired just like the police RK. Same gauges. Same wiring. Same connectors.
The wiring diagrams show all touring bikes the same except for radios, aux lights and amps.
